COMBINATION-TOOL- To all whom it may concern:

Be it known that I, .MARSHALL O. RAY- MOND, a citizen of the UnitedStates, residing at Rutland, in the county of Rutland-and State ofVermont, have invented certain new and useful Improvements inCombination- Tools; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in in art to which it appertains to make and use the same.

This invention relates to combination tools.

The object is to provide a tool, which shall combine in a compact,easily operated and thoroughly practical manner, means for keyseatingand center-lining shafts, a universal square, and a depth and surfacegage.

With the above and other objects in view, which appear as the nature ofthe invention is better understood, the same consists in the novelconstruction and arran ement of parts of a combination tool as wil? behereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, andin which like characters of reference indicate corresponding parts,Figure 1 is a view in perspective of a tool showing all of the variousparts, certain of them being detached; and Fig. 2 is a view in sideelevation, showing the parts of the tool assembled for center-lining theshafts.

Referring to the drawings, 1 designates the graduated shank orstock ofthe tool which is provided, as usual, in one side or edge, with a guidegroove 2. Combined with the shank for sliding movement thereon is a heador arm 3 with which is assembled a spirit level 4. This head straddlesthe stock and is disposed at right angles thereto, whereby to form atry-square, and is guided in its adustments and held fixed at anydesired point on the stock by a thumb or set screw 5 that works in thegroove 2.

In order to constitute the tool, a universal square, there is combinedwith the stock a -shaped head 6, that is used in centering shafts andother cylindrical bodies. This head, as shown in Fig. 1, straddles thestock and carries a set screw 7 that enters the groove 2 and thus clampsthe head at any desired adjustment. As usual, the arms of the head arewider than the stock to allow Specification of Letters Patent.

them to bear against the object being centered.

As above stated, among other objects had in view, is to adapt the toolfor use in keyseating and center-lining shafts, and for use as a depthand surface gage. The first object is secured by the provision of asliding clamp 8 that consists of a plate 9 carrying two ledges orflanges 10, and two arms 11 that straddle the stock and are secured atany desired adjustment thereon by a set or looking screw 12. One of theflanges, in this instance the upper one, carries a set screw 13 that isprovided for the purpose of clamping the attachment to be employed andthe lower one carries a hand or pointer 14.

When a shaft is to be key-seated or centerlined, a graduated scale 15 isassembled with the clamp and is held in place by the set screw 13, andby observing the relation occupied by the hand or pointer relatively tothe graduations on the scale 15, accurate measurements will be secured.The scale carries at one end a scriber 16 by which the shaft or otherobject is marked or scored.

To protect the stock from injury when the shaft is to be scribed, thereis a guard 17 provided which is slidably mounted upon the stock and isheld against movement by a set screw 18. When using the tool either forkey-seating or center-lining a shaft, the scale 15 is adjusted to bringthe scriber at the proper point, and the tool is then moved along theshaft with the guard bearing against it, thus securing the objectsought. The second object above defined, namely the adaptation of thetool for use as a depth or surface gage is secured by the provision of anovel form of scriber holder to be combined with the clamp 8. Thisholder consists of an approximately L-shaped arm 19, the inner end ofwhich carries a head 20 to engage the clamp 8 and be held therein by ascrew 13. Pivotally connected intermediate its ends to the outer end ofthe arm is a lever 21 that carries at its outer end a screw 22 throughwhich projects the scriber or needle 23 of the surface gage and, asusual, has one end pointed and straight and the other end pointed andcurved. The screw 22 carries a nut 24 by which the scriber may beclamped in its adjusted position.

In order to secure fine adjustments of the scriber after the nut 24 istightened, an adres justing screw 25 is provided that passes looselythrough the inner end of the lever 21 and is threaded into a boss oroflset 26 on the arm 19. Upon the screw 25 is placed a coiled spring 27that bears respectively against the lever and boss, and thus operates tohold the lever at the desired adjustment.

As the manner in which the tool is used,

.when in effecting surface or depth gaging is well understood, detaileddescription thereof is omitted.

It will be seen from the foregoing description that by the manner ofarranging and assembling the parts of the tool, that by slight changesand adjustments, all of the functions designed may be secured, andfurther that accurate work will result.

Having thus described my invention, what I claim as new is,

1. A combination tool comprising a stock, a head adjustably mountedthereon and carrying a spirit level, a centering head adjustably mountedupon the stock, a guard also adjustably mounted upon the stock, a clampadjustably mounted upon the stock, a scriber holder arranged to engagethe clamp,

said holder comprising an arm, an adjustable spring-pressed leverfulcrumed thereon, and a scriber clamp carried by the lever.

2. A combination tool comprising a stock, a head thereon, a clampadjustably mounted upon the stock, and a scriber holder arranged toengage the clamp, said holder comprising an arm, a pivoted springpressedlever carried by the arm, and a scriber clamp and bolt carried by thelever.

3. A combination tool comprising a stock, a head adj ustably mountedthereon, a guard also adjustably mounted upon the stock, and a clampsimilarly mounted upon the stock and embodying a plate provided withledges, a clamping screw carried by one ledge, a hand. or pointercarried by the other ledge, a graduated scale arranged to engage theclamp, and a scriber carried by one end of the scale.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
